Harelip nasal columella retention clip

Abstract

The invention relates to the field of medical instruments, and discloses a harelip nasal columella retention clip. The harelip nasal columella retention clip comprises two splints used for clamping the two sides of the nasal columella and a connector used for connecting the two splints; the connector is shaped like an arc, and the two splints are located at the two free ends of the connector respectively; the opposite sides of the two splints are provided with plate-type supporting surfaces; the top of each splint is provided with a first supporting part used for supporting the nasal alar cartilage, and the bottom of each splint is provided with a second supporting part used for being supported at the basis nasi. According to the harelip nasal columella retention clip, the verticality andheight of the nasal columella can be effectively maintained through the nasal columella fixing splints, and then the nasal shape obtained after an operation is maintained. By wearing the retention clip, the position and form of the nasal columella can be maintained truly and effectively, and the purpose of maintaining the harelip nose shape is achieved.

Description

technical field [0001] The invention relates to the field of medical appliances, in particular to a tool for supporting nasal alar cartilage after cleft lip and palate deformity surgery. Background technique [0002] At present, cleft lip and palate is a common congenital deformity of the maxillofacial region, accounting for 2 / 3 of all facial deformities, and the incidence rate is as high as 0.146%. Cleft lip occurs due to unfused or partially fused bulbous and maxillary processes. The discontinuous, ectopic attachment of the orbicularis muscle resulted in deformity of the nasal morphology on the cleft side as well. Nasal deformities can be corrected effectively through surgery, but cannot be maintained permanently. [0003] The nasal mold is an auxiliary medical material used after the surgical wound healing of children with cleft lip, and is accepted by more and more parents of children with cleft lip. The cleft lip nasal mold is a medical silicone product made accordin...

Problems solved by technology

[0005] However, the above two types of nasal models have the following disadvantages: 1) The maximum contact point between these two types of nasal models and the nasal cavity is at the edge of the nose, which does not play a role in supporting the alar cartilage; 2) Older patients wear nasal models after surgery It can seriously affect the appearance when going out, and it cannot be worn when going out, and it cannot be guaranteed to be worn continuously for a long time; 3) Both need adhesive tape to assist in fixing, which is likely to cause skin allergic reactions in children and affect the wearing time of nasal molds; 4) It is difficult for children to cooperate and easy to use If the nose mold is grasped by hand, the probability of loss is high due to parental care; 5) There is a problem of poor retention and easy falling off, which may easily fall into the mouth of too young children and cause the risk of accidental swallowing
